Electronic device and method for wireless communication and computer readable storage medium

A spectrum manager, in a wireless communication system, comprising:

• processing circuitry, configured to:
• acquire spectrum coordination information, from a first level spectrum manager at a higher level of the spectrum manager, for a second set of spectrum allocation objects managed by the spectrum manager, wherein the spectrum coordination information is used for coordination of spectrum allocation performed by the spectrum manager;
• perform, at least based on the spectrum coordination information, spectrum allocation for the spectrum allocation objects in the second set.

A spectrum allocation object, in a wireless communication system, comprising:

• processing circuitry, configured to:
• receive spectrum allocation information for use from a second level spectrum manager, wherein the spectrum allocation information is determined by the second level spectrum manager at least based on spectrum coordination information acquired from a first level spectrum manager at a higher level of the second level spectrum manager,
• wherein the spectrum coordination information is used for coordination of spectrum allocation performed by the second level spectrum manager.
